at'fthe city and county of-San Francisco and' State ofCalifornia, haveinvented `a new and usefullmprovement in Paper-Disk Separating andFeedingDevices, of Whichthe followlngxls a specification.:

This 'invention relates to a paper disksep- :ir-ating and'feedingdevice,`andY especially to al' device for delivering paper-disks orblanksto auring liner cutting and assembling machine, such as shown inmy 'copending appli cation entitledfRolling cutter, led August 28,1916,Serial Number 117,188. v-

The applica-tion above referred to relate tofan apparatusfor cuttingyring liners from Va continuouspaper web and applying the .ring liners,when cut, to can` ends. When` cutting,` ring liners from acontinuousweb, it is obviousthat for` every liner cut a central core orblank isformed which 'would cause ka considerable Waste unless utilized. inactual practice I have found that the blanks produced may be re-used togreat' advantage for cans of smaller diameter and that the' blanksagain'formed may be used for cans of stillsnialler diameter, thusreducing paper waste to a: minimum.

The presentinvention is particularly de signed to handle paper disks 'orblanks,` and einbodiesa magazine-or a holder forfthe reception of thesame, a. separating device, and means for feeding or deliveringl theblanks one by one to a series of cutting dies.

The invention yalso. embodies other features which will hereinafter bemore Vfully described, having reference to the accompany-v ingdrawings,in which* Y Fig. 1 isa side elevation, partly in'section, of airingliner cutting` and ,assembling ma! chine, showing` the application oftheinvention.

These rods ,extend upW-ardlylon an langl"efand A the paperdisksarefstacked between the rods, as s hownat'2l). Formed on the inner end,of each rod is va stop. member 21.5'. ,'llfiese ioo by a suction cup,such as shown at 22. This.l

suctiongcup is mounted invsuch a manner that reciprocal movement may beimparted thereto, that is, its range of movement is shown in F ig. 1. Iteither assumes the full line position shown, or the dotted line posi-Y Ysaine with relation to the end ofthe blank tion shown. Y Y

This movement is transmitted in the following manner: Suitablysecured'inbrackets 23, carried by the base plate, is a pair of Vguiderods 24, and slidably'mounted on each guiderod is a cross headmember`25. j Connecting the cross head members is a cresswise extendingrodk 26, and a'd'justably se-` cured thereon is a holder 27, throughywhich' extends a tube 28. Suitably secured' onthe upper end of thetubel'is a suction cup 22, and formed near the 'lower end of the tubeisa vent opening 29,v which is normally closed by means of a valve 30.This v alve is pivotally mounted, as at 31', in a bracket secured onthe'V tube 28, and the valve is provided with alever extension 32,7whichis adapted to engage a' stop member 33. This stop mem- 4 ber isadjustably attached to the bracket 11,

as' indicated at 34, and its function will hereinafter be described;Secured to the lower end of theV tube is a flexible rubber hose 35. Thistube is connected with a vacuum pump or a similar device, not hereshown.

Extending crosswise .through the 'bracket 11 and vjournaled therein is ashaft 36, and secured on said shaft is a pair of crank arms 37.Connecting said crank arms with the cross shaft26 is a pair of links 38,`and secured on one end of the shaft 36, is a crank arm" 39 which isconnected with a crank pin 40 by means of a link 41; The crank pin 40 issecured to a disk 42, which is secured on a shaft 43 supported in ajournal member 44, and rotary movement is transmitted to they shaft 43from the main driving shaft 4, through a connected gear train, such asinj dicated at45 and 46.

' Inactual operation, vwith power transmitted' to rotate the die wheel5, it Vshould be obvious that continuous rotary movement will betransmitted `to the shaft 43 and the crank disk 42; similarlyv that anoscillating movementy will be transmitted to the shaft 36 through meansof the link 4and the crank arm 39. This oscillatingV movement is in turntransmitted through the crank' arms' 37 and the links 38 to the crossheadl members 25 and the cross rod 26 connecting the saine, and as thisrod supports the holder 27, the tube 28 and the suction cup 22,l itshould be'obvious that a reciprocal movement will be'transmittedthereto. The tube 28 supporting the suction cup passes' Laer/,sis

through a slot 7a, formed in the arm 7, and its angular position may be'adjusted by turning the holder 27 upon the rod 26. That is, the holderis split, as indicated at 27 a, and a screw extending therethroughlforms ameans for tightening the holder in any angular adjusted position.This adjustment is of importance as it permits vertical adjustment ofthe suction cup Vand the connected tube, and also angular adjustment ofthe holder and the platen 9.

l/Vith' the suction cup in the position shown by dotted lines in Fig. 1,suflicient suction will be exerted to cause the foremost disk or blankin the stack 20 to adhere to the suction cup. This pulls the lower endofthe blank away from the stop members 21 and also the upper stopmember, indicated atV f 21a. tube 28 Aand the' suction cup 22 brings thecup, together with the blank adhering thereto, into position, directlyin front of the platenQ where the upper edge of the blankV is engaged bythe die 14 as 'this passes over the platen 9, as indicated by dottedlines at 20a; the position indicated being that assumed when the blankis released b-y the suction cup. The stop member 33 engages the lever 32a moment previous to assumption of the dotted' line position indicatedat 2Oa and thereby breaks the vacuum or suction in the cup 22 t0 such anextent that the blank isv operation and the waste produced is dis-`charged from the machine in the direction of arrow a.. The suction cupis, in the meantime, moving back toward the blank holder and againassumes the dotted line position shown, where it removes the next blank.It then travels forward toward the platen and reaches this in time todeliver the blank to Forward movement of the holder, the

the next die. The dies 14 are equally spaced c about the circumferenceof the die wheel and a certain time interval is thus permitted betweeneach die. This time interval per- `mitting` one complete reciprocationof the feeder, a blank is, therefore, always in position Aas the dieapproaches the platen 9 and one complete reciprocation is transmitted tothe feeder during the approachof each die.

The blanks employed are circular and may first be obtained .when cuttingring liners for larger size can ends, and, for instance, vwhen employinga Webfeed, suchas shown 1n my 1 co-pending application lreferred to.vThese blanks shown' in Fig. 4 are stacked, as indicated at 20, betweenthe rods 17, 18- 'and `19.l Asthese rods are inclined,

it is obvious that they'willsettle downwardly toward 4thefstopfmemb'ers'2l and f inclined position oflthe rods supporting the same, and,secondly`due `to they slight vibration caused when the `machine is inoperation. f The blanks, 'when delivered to the dies, arecut as shown inFig. 4;; that is, Aa

rin liner is forlmedysuch as shown at 50, which isr'etained'by thedieuntil it is transferredtoa can" end. A central blank V5lf'is alsoformed and also an exterior waste strip 52. yThel central blanks aresaved and may v be reused for can: ends of still smaller diameter;theholder -employed for their-reception beingsmaller than' that shown inthe present instance as the Y diameter is reduced; The blanks maybe cutdown from one size to another until the ,smallestV size can endisreached and paper waste is vin this manner reduced to a minimum. Thesame feeding devicemay be employed in eachinstance, the only changerequired being'the substitution of a paper blank holder or an adjustmentremoving' the same from the stack.

which permits the rods to be radiallypositioned as the size of theblanks decrease.

v-The importance of permitting adjustment is, Ias the size of the blankdecreases it should be obviou'sfthat vadjustment of the suction cupshould be permittedas itis desirable to engage the' blanks near thelower ends wen n gagement of the blank at the time vofremoval at a pointnear the lower end permits the-blank to be pulled free; first, withrelation to;the lower stops 211; and, secondly, withlr'elatio'nto-the'upper stop 28. In other words, theforem'ost'blank i'sgraduallyreleased 'with relation to the stops and ideal separation isl therebypermitted. Adjustment of vthe-stop member 33Vis also of im?portancekas'it permits suction release of the blank; 20a'wheneveridesired. f y

The present feeding device 1s exceedingly simple asit avoids`intermediate transferring means, registering Lmeans and other devices.A

By referring to'llig. 1, itfcan be'seen that they feeder removes'ftheblanks from the stack in successive order and delivers them directly tothe cutting dies, thus avoiding the use of intermediate mechanisms suchas' areusually employed in feeding devicesof this character. V
